The Best Way to Use Goodreads?

I’ve seen a number of posts recently on managing your Goodreads shelves, trimming down your digital TBR, etc.  This got me thinking: am I using Goodreads to its greatest potential?

I have been on Goodreads for years – I’m pretty sure I joined in 2008 or 2009 when the site was in its early years.  I mainly use it to keep track of the books I’ve read or am currently reading, set my yearly reading challenge goal, and enter the occasional giveaway.  I feel like this is just skimming the surface of what the site can do. It looks like a number of authors have joined up and there are plenty of users that have huge followings for their reviews.

I’d love some advice from the experts: you guys! What are your favorite features of Goodreads?  What am I missing?  Do you have any suggestions for making the most out of the site?  Goodreads has changed so much over the years that I feel like I’ve been left in the dust!
